COMBINED LISTER AND DRILL.

SPECIFICATION forming part of Letters Patent No. 407,084, dated July 16,1889.

Application filed September 5, 1888. $e1'ia1 No. 284,647. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM A. LoUeHRY, of Odessa, in the county ofBuffalo and State of Nebraska, have invented new and useful 5Improvements in a Combined Lister and Drill, of which the following is afull, clear, and exact description.

The invention relates to machines for planting seeds, such as corn, &c.

IO The object of the invention is to provide certain new and usefulimprovements in a combined lister an d drill, by which the usual subsoil-plow is entirely dispensed with, and by which the edge of thetrench is left at an angle instead of perpendicular, so that the grasswill not soon appear at the joint of the turn of the furrow, as is thecase generally, and the surface-soil is well buried by the furrowswithout any break or thin spot favorable to the germination ofweed-seed.

The invention consists of adj ustable curved concave blades oradjustable concave revolving disks attached to the inside of themoldboard or beam of the plow.

The invention also consists of certain parts in detail, and combinationsof the same, as will be hereinafter fully described, and pointed out inthe claims.

Reference is had to the accompanying o drawings, forming a part of thisspecification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a plan viewof the same, and

Fig. 3 is a sectional end elevation of the same on the lines X X of Fig.l.

The improvement consists of two adj ustable curved concave blades A A,each provided at its upper end with a shank B, fitting into a keeper(),and secured therein by a setscrewD or othersuitable means. Each keeper 0is fastened by bolts or other devices to the inside of the mold-board E.of the plow F, forming part of the combined lister and drill G of anyapproved construction.

Instead of fastening the keeper 0 to the mold-board, as above described,I may fasten the same to the plow-beam G.

The blades A are curved downwardly and extend rearwardly toward eachother, as plainly shown in the drawings; but the lower ends of the saidbladesAleave sufficient space for the seed and to form an oval furrow inbottom of trench. Directly behind the lower ends of the blades A, andbetween the same, is held a groove-wheel II, mounted to rotate insuitable bearings fastened to the rear end of the plow-beam G, andserving to tamp and leave in an oval form the ridge in the bottom of thetrench formed by the blades'A.

The wheel II imparts motion to a suitable device for operating the slideI, connected with the seed-box J, located on top of the plowbeani G,directly above the blades A, so that the seed is discharged into thetrench formed by the plow F, and is covered up by the ridge formed inthe trench by the blades A.

The ridge formed by the blades A is tamped and left in an oval form bythe groove-Wheel II, as before mentioned, so that the seed 7o planted inthe trench will readily germinate in a dry season, and at the same timepreventing an early germination of weed-seeds, this form of ridge inbottom of trench allowing an earlier cultivation of corn, &c., by theuse of the harrow or the cultivator, than can be obtained by any otherform of lister and drill now in use.

It will further be seen that the soil thrown over by the plow F buriesthe surface between the trenches without any break or thin spot to allowthe early germination of weedseeds.

Having thus described my invention, I claim as new and desire to secureby Letters Patent l. The combination, with a listing-plow, of concaveand inwardly-curved blades secured to the plow, substantially asdescribed.

2. The combination, with a combined lister and drill, of the concave andinwardly-curved blades A, adjustably secured to the inside of themoldboard, substantially as herein shown and described.

a. The combination, with the combined lister and drill, of twoinwardly-curved and concave blades attached to the inside of themold-board extending downward toward each other, and a grooved wheelheld on the 00111- bined lister and plow in the rear of the said blades,the said wheel imparting motion to the slide of the seed-box,substantially as shown and described.
